"The Wand-Lighting Charm is simple, but requires concentration. Take care not to accidentally set your wand alight as damage of this kind can be permanent. If in any doubt about your abilities you would do better to buy yourself a magic lantern."

However, Garvin Lügner, a German wizard, claimed to have been the one who invented the spell, while he was developing his Instant Darkness Powder. It later transpired that Lügner had been lying about the invention of the charm, and that his Instant Darkness Powder did not do too much more than slightly dim the lights.[3]

Effects

"To illuminate the end of a wand, the caster must call out the incantation "Lumos." If correctly incanted, the end of the wand will then illuminate and cast light in the immediate vicinity of the caster. It can also be used to illuminate unseen entrances."
